Functional Diagram
General Description
The HMC-MDB207 is a monolithic I/Q Mixer which
can be used as either an image reject mixer (IRM)
or a single sideband upconverter. This passive
MMIC mixer utilizes two double balanced mixer cells
and a 90 degree hybrid. It is fabricated with GaAs
Heterojunction Bipolar Transistor (HBT) Shottky diode
technology. For downconversion applications, an
external quadrature hybrid can be used to select the
desired sideband while rejecting image signals. All
bond pads and the die backside are Ti/Au metallized
and the Shottky devices are fully passivated for reliable
operation. The HMC-MDB207 I/Q MMIC Mixer is
compatible with conventional die attach methods,
as well as thermocompression and thermosonic
wire bonding, making it ideal for MCM and hybrid
microcircuit applications. This compact MMIC is
a much smaller and more consistent alternative to
hybrid style Image Reject Mixers and Single Sideband
Upconverter assemblies. All data shown herein is
measured with the chip in a 50 Ohm environment and
contacted with RF probes.
